Abstract

The concept of environmental problems expanded in terms of space and time, having started from public nuisance at the local level, been expanded to the global level because of the mass consumption of energy and natural resources, and included an issue to ensure equal opportunities of the future generations. In parallel, major agenda around sustainable development evolved from achieving balance between the environment and the economy, to realizing green economy in which environment protection is recognized as a driving force of economic development, and to realizing a fair society where the wealth from the economic development be distributed in a fair and equitable manner. SDGs have those values: 1) as they were adopted at UN through a democratic process, each national government developed its national implementation plan; 2) they fit quite well to the real situation of the world that is composed of countries of various levels of development; 3) understanding of mutual relations among 17 targets are promoted; 4) they are localized at a community level; and 5) they demonstrate that pursuing environmental conservation directly contributes to realize sustainable economy and society.
